' 'Applidation filed April s, 1921i Saaiwa'Maa I Be it known thatLIV'SAMUEL C; VAUorIN,

' a citizen of the United States, residing at Charlotte, inthecounty'otMecklenburg and State of North'Ca'ro-lina, have'invent'ed 1new and useful"Improvements in Journal'- Box 'Jae-ksjuof which'jthefollowing is a specification." a 1 1 I This invention relates toimprovements'in journal-box jacks and has for an object the provision ofa jack of this character, by

I means'ot which the journal boxes ofrailway necessity of adjustmentwj"without raising the carwheels;

An object of the invention is the provision of means rigidly"secured-to'the'jack for. engagement with the end of the-journal to cars maybelifted for the removal and'insertion of "the usual wedges and brasses,

prevent the latter flO'lll' raising the said means being constructed toengage journals of difl'erent sizes in a manner to prevent accidental,displacementand without the Another object ofthe invention is theprovision of a journal-box jack which, when in'use, is arranged to oneside of the vertical center of the journal to permit ready a'ccessto theinterior o the box? I to be hereinafter more fully described, illus- 2form of jack.

c showing a still With the above and otherobj'ects in view, theinvention further includes the following novel features and detailsofco-nstructlon,

trated in the accompanying drawings and pointedout in theappended claim.

In the drawings':

Figural is a sectional View of ajournal bearing with the inventionapplied thereto. a Figure 2 is a horizontal-sectional View taken on aline-above the wedge. .Figure 3 is a section on the l1ne3--3'of Figure 1p c v, a

Figure 4 is an enlarged detail section on the line 44l of Figure '1.

Figure 7 is a view similar to Figure 5 jack. q a

Figure 8 is a section on the line 88 of Figure 7. 1 v v 1 Figure 9 is afront view illustrating the form of jack shown in Figure 1 with theoffset feature eliminated.

Referring in detail to the drawings, wherefurther modified form of inlikcharacters of: referencedenote corresponding' parts, the jack isshown inconnection with an-ordinary journal bearing which includes a box10; the" usual bushing 11 and wedge'12. In the removal of the wedge andbrass from thebox, the latter isfvert-ically liftedand it is desirableto provide some means torjpreventing the oar axle and wheel fromraising, at the same time, inorder that thejournal, and the'bea-r- 4 1ing may be separated for the removal of the wedge and brass! It isfurther desirable that the 'parts *be positively held so" as to preventslipping when the jackis in operationand for-thispurpose it is ofimportance that the engagement between the jack and the; journal bepositive. so that accidental displacement will be ofacciden't'eliminated. j I

With this in view; the invention provides prevented and danger a jack.which is formed of a substantially u shapedmember 13 whichincludes-upper and lower substantially parallel arms 14 and 15, whichare. connected by a vertical bar 16. -The arm 15 is provided with athreaded opening 17 forthe passage ofa screw-1S, whose upper end isprovided with member 19 is adapted to engagover the vertical center ofthe journal. soas to provideadirect downward thrust when the j aok isoperated to raise the' journal box and owing to its construction willfit over collars a .90 I journal oraxle-22. The journal engaging ofdifi'erent sizes and at thesametimeproi vide a. sure andpositive' griptheflanges formed by; the groove 20 engaging upon opposite sides of thecollar.

In the operation of the jack, the screw 18 i has mounted thereonasocketed'member 23 which receives the screw, the latter at this pointbeing provided with teeth 24, for engagement with oppositely extendingspring dogs 25. One ofthese dogs engage the teeth 24 to rotate the screw18 in one direction,

' while the opposite dog is engaged to'provide for arotation in theopposite direction, an adjustable stop 26 which is carried by thesocketed member .23 providing for holding either of these dogs in anoperative position.

- An operating handle 27 may be inserted within the socketed member toprovide proper leverage.

' In order to permit easy access to the interior-f the journalbox, thebar 16 which connects the upper and lower arms 14 and 15 is offset asshown at 27' so that the said arm is disposed to one sidelof thevertical center of the bearing.

In the operation of the invention, the jack is positioned as illustratedin Figure 1 of j the d rawings and when (he lever 27 is oper ated, thescrew 18 willbe rotated to raise the box 1Q while engagement of themember lflover the collar of the car Journal or axle I will prevent thelatter from being raised;

As before stateditis essential that during the. operation of jacking upthe box, the parts must be held in apositive manner to prevent slipping.This is-provided for by having a rigid connection between the jack andthecollar 21. This engagement of tl e collar and jack is thus preventedand any tendency of the jack to slip from beneath the journal box isalso prevented; I 'lnftlle form of themvention shown in Figureso and 6,the screw '18 has mounted thereon a gear 28 which threadedly engages thescrew, The screw also extends through a threaded opening provided in thelower arm l" of the jack and througha similar opening formed-in an arm29 which extends from and is parallel to the outer end of the arm C Thegear QSis positioned between the arm 15 and the arm 29 and when thisgear is-rotatedjvertical movement will be impart'edto the screw 18. Therotation of the gear 28 is accomplished through the medium of a worm 30which is mounted upon a shaft 31, the latterbeing rotatableinibearings32 extending from the arm 1.5. The shaft '31 is provided atits end with an operating-lever 33, which may have a ratchet engagementwith'the shaft 31 to provide for rotating the latter.

In Figures '7'Hand' 8, the construction is somewhat the same, exceptthat instead of having the operating handlearranged adjacentthebar-which connects the upper and lowerarms of the jack,the'saidoperating handle. is disposedlaterally or to one side of theouter end of :the arm 15. In this form there is provided a beveled gear34 ing from the jack.

--which is engaged by a beveled pinion 35,

the latter being carried upon a stub shaft 36 which is mounted inbearings 37 extend- The shaft 36 is provided with aratchet engagedoperating lever I 38 to provide for rotating the same. Like the form ofthe invention shown in Figures 5 and 6, the form shown in Figures 7 andS has its shat 18 threadedly engaging the gear 3a and the bearings"provided in the arm 15 and the inwardlyextending parallel arm 39. p I alathe .form of the invention shown in liligure f), the construction issimilar in all respects to that described in connection with Figure '1;except that the barlO which conuects the upper and lower parallel armsof the jack is arranged substantially in a line withthe vertical centerof the journal hearing and not-offset as previously described.

q The invention susceptibleof various changes in its form, proportionsand minor details fol construction and the right is herein reserved'tomake such changes as properly fall within the scope vof the appendedclaim.

Having-described the invention what is claimed is L I "A journal box ackcomprising a substantially U-shaped member presenting horizontal upperand lower parallel bars connected by a vertical bar ofiset laterallywith-respect to the parallel bars, an integrally formed head depending,from adjacent the free end of the: upper-bar and presenting a groovefor the reception of the outer end of a car journalor axle, a bearingarm integral with the lower horizontal bar and extending inwardly fromadprcent the outer free end thereof in spaced parallel relationto theupper face of the bar, a screw extending vertically throughalignedopenings in the said arm andlower horizontal bar, a gearpositioned forrotation between the said arm and lower horizontal bar andhaving a central bore threadedly engaging'the said screw, a shaftjournaled longitudinally of the said lower bar in bearings extendedlaterally from the lower bar, a worm on one end of the shaft engagedwiththe said gear, and an operating lever at the opposite end of theshaft. i

In testimony whereof I attix my signature.
